Looking for a PC/104 system (or similar) with at least 2 20+ bit A/D's and a couple of 16+ bit D/A's. Also needs to have Ethernet either built in or as a expansion.
Can anyone offer a suggested vendor they have used?
Thanks!
I have a concept that should achieve 95-98% efficiency according to the analysis. The switching is mechanical, i.e. it couples the sensor fiber optic to the different input fiber optics one at a time. Two sets of ball lens are used to collimate the light & re-focus it into the mating fiber.
If...
Hi,
I have a project that needs to multi-plex a number of fiber optic cables which collect broad band light sample information and present it to a single sensor. There is no "data" on the fiber optic, we will be just looking at the spectral distribution. Low switch speed is not a problem, low...
gyro design
Here are a couple more sites to look at;

The later one is a single axis, but pretty inexpensive.
Good Luck
There are a number of optical methods for determining the spectral content (i.e. color) of an object.
Perhaps the simplest (at least conceptually) would be to use a band pass filter designed to block the accepted color spectra and pass only the reject color spectra. Then a simple photo...
ds18b20 subzero
Are you looking for "accuracy", "repeatability" or "sensitivity"?
These are three very different concepts that frequently are confused or lumped into a simple requirement for "accuracy"
Accuracy: A measure of how close a measurement is to a defined standard - such as the 1990...
oscilloscope rs232 interface
Hi,
I had no problems with the bitscope or home.wxs links.
I agree that the dsoworld link seems to be gone.
If you are linking on the link & expecting to go there - it does not work that way. You need to edit the link to add missing or remove extraneous...
Motor w/ Position Feedback
If you decide to do a mechanical feedback system instead of non-contact measurement, I might suggest looking at either the Maxon line of brushless motors. And/or the Smartmotor line of brushless motors & controllers.
We have used Maxon motors to provide an optical...
Distance Sensors
There seems to be a great deal of interest in ranging and distance measurements. Perhaps the group would find this comparison of different methods of use;

And for a good source of various low cost sensing components, try;

servo controller schematics
They are a bit expensive, but I recommend you look at the SmartMotors from Animatics Corp.
They offer a combination brushless motor/encoder that has a RS232/RD485 addressable controller that will drive the motor to a specific position, at a constant speed, at a...
Hi,
Sorry if this is a duplicate message.
If you are not an optical designer (and I am not), you might consider trying TracePro.
It is easy to use and allows you to add antireflection coating, etc.
I find it is good for visualizing the rays, especially if you have a stray light problems...
Hi,
I am putting together an EL panel for an instrument panel backlight. It has a 12 VDC input and a 170 VAC EL panel drive.
I have been unable to find any info on how to add a dimming feature. I am assuming it is simply a pot inline on the output. But what resistance? Is that really where it...
